Black Screen After Kakao Games

Hello! i was originally playing on official EU serv of BDO with client version 408, since the server was updated to the 408 i installed the patcher and logged in / Started the game, i got a weird problem tho, The Kakao Games message Appeares without a logo ( it does on official game, no idea if it is supposed to appear here or no) And after a while, the Message disappears and i get a black screen, i left it running for 30min but didnt load, retried several times and sometimes it would randomly crash.
Any suggestion on how to fix this? Also i would like to know where the Game settings ( resolution etc...) are stored, maybe tweeking em a little will help
